Rider size: The Aurora will accomodate riders from 160 cm the
190 and maybe a bit more. One of our testers is 180 cm and weighs in at 100
kg and he has room to spare. The width at the shoulders for a 187cm tall rider
is 56cm(22").

Luggage capacity: We have measured the volume behind the seat
by filling it with foam chips. This volume was 120 litres. There is still
a bit more storage space under and beside the seat, another 40 litres. For
a couple of pictures of the foam and camping gear see the August-september
2006 update.

Suspension: the two rear wheels have a composite spring providing
over 5 cm of travel. Spring stiffness can be modified to suit the rider. Front
wheel has no suspension but is fairly lightly loaded so we fell it is not
necessary.
